The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth. The geometry for the house was imported from a CAD file and a flat terrain was placed underneath the house.
The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.
This example analyzes the coupling between four circular patch antennas mounted on the sides of a Boeing 757. The antennas transmit and receive at a frequency of 2.4 GHz. Coupling between each antenna is characterized using XGtd’s S-Parameter output, which can be displayed in the user interface or exported to a v1.1 Touchstone file.
